Effect of cannabis on the onset of psychosis
Researchers from Spain and Boston studied the relationship between age and cannabis use in patients with a first psychotic episode.
First, the details.
- 131 consenting patients (age 15 to 65 years) with a first psychotic episode requiring inpatient psychiatric treatment were interviewed.
And, the results.
- Increasing use of marijuana was significantly associated with a reduction in the age at onset of the first psychotic episode.
- The effect of cannabis use on the age at onset could not be explained by the use of other drugs or by gender.
- The finding was similar in the youngest patients, suggesting that this effect was not due to chance.
The bottom line?
The authors concluded, “These results point to cannabis as a dangerous drug in young people at risk of developing psychosis.”
